OpenJDK Mercurial Transition Update 4

Update 4

We tried very hard to split out corba, jaxp, and jaxws in Build 21
but didn't make it, however they just now got integrated
into Build 22.
This splits out an additional 6,000 files or so from the primary j2se
workspace.
This would not have been accomplished at all without
the dedicated hard work ofSeema,
thank you Seema.

So with Build 22 we will now have:

control

Primary control build make files.
Builds a complete or partial set of the components listed below.

Independently buildable hotspot sources, mostly native code but
some Java code.
It does need access to a BOOTDIR javac during a build.

j2se

Independently buildable jdk, with access to a JDK_IMPORT_PATH.
Requires a BOOTDIR jdk and optionally the langtools bootstrap tools.
You can point it at the dist areas of
langtools, corba, jaxp, and jaxws, for these classes,
or it will pull the classes out of the
JDK_IMPORT_PATH rt.jar and tools.jar.

The langtools component is built with the BOOTDIR jdk and creates
the jdk contribution files (dist/lib/classes.jar and dist/lib/src.zip)
for the resulting jdk image being built, plus bootstrap tools that
can be run with the BOOTDIR jdk for building the complete jdk
with the latest class versions etc.

The corba, jaxp, and jaxws components are given a BOOTDIR jdk to
build with (and optionally the langtools bootstrap files when
doing a full control build). All the components create contribution
files (dist/lib/classes.jar and dist/lib/src.zip).
Corba also contributes some special jdk image files (dist/bin.zip).

Build 22 continues to be our target for the last JDK7
promotion built via the TeamWare workspaces, the Build after
this one would be done via Mercurial repositories.
There is some risk to this target, and it's possible it might slip,
but it continues to be out target, and the momentum is building up.

There will still be a few SCCS keywords in the
Mercurial sources at first, but
these should be harmless. We'll continue to clean up the source as
we go.
